Olin [163]

Answer:

b)\,\frac{dW}{dt}=kt\sqrt{W}, \,W(0)=10

Step-by-step explanation:

Initial number of sick wolves = W(0) = 10

At time t, no. of sick wolves = W(t)

Given that disease is spreading at a rate proportional to the product of the time elapsed and the square root of the number of sick wolves:
